With Premiere Rush going away...will Adobe have a faster smart phone upload?

Now before all the Adobe moderators come after me for this comment, just listen.  Now, I know that Rush is going away in October.  But what is going to replace it?  I have a laundry list of issues I had with Rush, but I don't want to bore the Adobe community with my ideas and issues.

I have tried numerous times to create a video in Rush and upload it directly to my YouTube channel, and each time it has failed.  Why does this keep happening?  Then I have to save it to my photos on my iPhone and try to upload it to my YouTube channel.  However, each time I return to my computer, the video fails to upload.  It just CONTINUALLY states, "Video is processing."  I uploaded this video last Tuesday, and it is STILL processing?  Something feels very SUS.

The crazy part is when I shared it to TikTok directly from Rush, it uploaded in less than a minute.  So it appears TikTok is more advanced than Adobe?

I mean the video is almost 7 minutes long and 591 Mb.  I just plugged my phone into my Dell Precision workstation, and after a few hiccups, I couldn't find the video on my iPhone ANYWHERE.  

So next, I ended up sharing it to my Google Drive and after two attempts it FINALLY uploaded.

Now, since the original video is in "Video is processing" jail, I will have to re-upload the video to my YouTube channel and delete the one that is still processing.

I know with Rush being shutdown soon, I doubt I'll get a response.  But it would be nice to know what the answers are and what Adobe is going to replace Rush with.

Good night.
